Honestly, I see nothing wrong with FF in the morning and dry for the rest of the day if that works for you. I'm not in the "all or none" FF camp. I feed one or the other (or both) depending on how much time I have on any given day.
As far as spoiling goes, I suggested that it wouldn't spoil in a day for two reasons.
1) I've read it in this thread a few times that it doesn't spoil, and
2) I've seen it dry up here in a half day in temps in the 85-95 range.
Now, I don't know if it spoils at all (maybe it does?)...though it could certainly grow mold. I'm just not sure that it could do that in the temps you get before it would dry up. I'm just guessing here- our situations are vastly different and I'm sure FF behaves differently for me than it does for you. I mix a very dry FF, yours may have more moisture than mine.
One thing is for sure...I don't envy you those temps! I lived most my life in south Texas,geI'm familiar with brutal summers. OUCH! I don't miss them.
